THE CONFIGURATION OF PRODUCTS AND SERVICES WITH MULTIPLE SUPPLIERS (CAWICOMS) aims at the next generation of web-based configuration applications that cope with two challenges of today’s open, networked economy: (1) the support for heterogeneous user groups in an open-market environment and (2) the integration of configurable subproducts provided by specialized suppliers. This article describes...

Seamless service continuity means maintaining service execution whatever environment change. Before processing service adaptation for this new environment context, the optimal service configuration has to be computed. We propose an approach to automate the planning process that determines the optimal service configuration with environment context and user preference. This approach is based on c...

The Computational Linguistics and Information Processing lab at the University of Maryland participated in two TREC tracks this year. The Microblog Real-Time Filtering and the LiveQA tasks both involve information processing in real time. We submitted nine runs in total, achieving relatively good results. This paper describes the architecture and configuration of the systems behind those runs.

Eclipse is a heterogeneous multiprocessor architecture for high-performance media processing, including high-definition MPEG encoding/decoding. The scalable architecture framework concurrently executes media processing kernels in function-specific multi-tasking coprocessors and a media processor, communicating via on-chip memory. Eclipse instances combine application configuration flexibility w...

This paper discusses a proposed processing technique for combining video imagery with auxiliary sensor information. The latter greatly simplifies image processing by reducing complexity of the transformation model. The mosaics produced by this technique are adequate for many applications, in particular habitat mapping. The algorithm is demonstrated through simulations and hardware configuration...

The Circuit Switched Tree (CST) has been shown to be an important interconnect for dynamically reconfigurable architectures, on which several problems have extremely fast solutions. A vital component of communicating through the CST is the configuration of its switches. In this paper, we present configuration algorithms for two classes of CST communications: oriented, well-nested sets and multi...

typically, two configurations are used for energy harvesting, with different advantages: piezoelastic and piezomagnetoelastic. best performance of piezoelastic configuration is limited to its narrow bandwidth around the resonance frequency. if the excitation frequency slightly deviates from the resonance frequency, the power-out is severely reduced. to overcome this, the piezomagnetoelastic has...

This paper presents a general methodology to decompose the processing of relational queries into functional units. Each unit consumes a constant CPU usage, which depends on the DBMS and system configuration, but not on the database or the query. We describe how to measure the unit CPU consumption, as well as how to use it to predict and interpret query time. Two DBMSs were tested to validate an...

Narrow passages and orientation constraints are very common in manipulation tasks and sampling-based planning methods can be quite time-consuming in such scenarios. We propose a method that can learn object orientation constraints and guiding constraints, represented as Task Space Regions, from a single human demonstrations by analyzing the geometry around the demonstrated trajectory. The key i...

In an immersive virtual environment, observers fail to notice the expansion of a room around them and consequently make gross errors when comparing the size of objects. This result is difficult to explain if the visual system continuously generates a 3-D model of the scene based on known baseline information from interocular separation or proprioception as the observer walks. An alternative is ...
